This invention relates to a thread board frame, the invention relating more particularly to frames for spinning wool. Itis one obj ect of our inventionto provide a thread board and guide adapted .to resist the excessive wear caused by the friction of wool yarn. y

A further object is to provide a construction of thread board and guide which will prevent accidental unthreading when yarn having` either a right hand or a left hand twist 1s used.

Our invention further relates to the provision of a construction in which theyarn 'guide may be conveniently adjusted relative to the thread board and by which said guide may be e'ectively held in operative position.

A preferred form of our invention is shown my. in the drawings in which Fig. l is a plan view of parts of a thread board embodying our improvements;

Fig. 2 is a side elevation, looking in the direction of the arrow 2 in Fig. 1;

Fig. 3 is a sectional front elevation of one of 'the thread board members, taken along the Fig. 4 is a similar view, taken along the line 4`4.in Fig. 1;

Fig.v5 is a-perspective view of a porcelain Fig. 6Ais a therefor.

Referring to the drawings, we have .shown a portion of a spinning frame 10 to which a y'perspective view of a holder thread board rail or support 11 is bolted. YWe

have also indicated the position o f drawing rolls 12 and 13 vand a ring rail 14 supporting the usual spinning rings 15 and travelers 16 by which the yarn Y is wound on the bobbins B; all of these parts being of the usual l construction A plurality of thread board members 2O arehinged at 21 on the rail or support 11 and aresupported in substantially horizontal.'

position thereby. The members 2O may be swungfback to the dotted line position in Fig. 2, as is usual when doing the spindles.

Blocks24 are Secured to the hinges 21, as by screws 25 Y and the thread board members 1928. Serial F0. 295,807.

A porcelain thread guide is. providedV for each member 20, each guide having a central opening 31 and an inclined threading slot 32 in its front or outer face. The guide 30 is retained in a holder 35 (Fig. 6) having a recess 36 in which the yarn guide is seated and retained. v

The holder also has a shank portion 37, adapted to extend into a slot or recess 38 in the upper face of one of the blocks 24. 'The recess 38, however, is of slightly less thickness than the block 37, and is also of slightly greater width. l

he holder'35 is freely adjustable forward and rearward to centrally align the opening 3l over the axis of the bobbin B, and the yarn guide may also be slightly adjusted sidewise by swinging) the holder in the slot 38, such movement eing permitted by the greater width of the Slot.

i-When the bolts 28 are tightened, the thread board memberor plate 20 is drawn 'against the shank 37 and the holder 35 is firmly secured thereby.

The thread board member 20 is preferably formed of sheet steel and has a central opening 40 .(Fi'g. 1) and a threading slot 41 extending inward from the front or outer edge of the plate. The slot 40 is inclined to the left,`as viewed in Fig. 1, providing a hooklike projection 42, which is preferably bent With the construction shown, it' is found.

that -t'he thread board and yarn guide are conveniently threaded by passing the thread to the left around the hook 42 and then to the right into alignment 'with the sloty 32, by which the thread is admitted to the central passage 31 ofthe procelain yarn guide. It is found also that the thread cannot be readily displaced from the yarn guide and thread board memberl during the operation of the machine, whether,` the thread is right hand twist orleft hand twist, and in this respect our invention is a very substantial improvement over the previously used constructions Awhich were very likely to unthread when the direction of twist was reversed.

Having thus described our invention and the advantages thereof we do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but whatwe do claim is 1. In a spinning frame, a thread board having a yarn threading and guiding opening therein, a yarn guide centered under said opening, said yarn guide having an inclined threading slot at the front thereof, and said thread board having an upwardly displaced hook overlying said slot.

2. In a spinning frame, a thread board having a threading and yarn guiding opening therein, a yarn guide centered under said opening, said yarn guide having a threading slot in its front face inclined upwardly and to the right, and said thread board having a hook portion overlying said threading slot and inclined upwardly and to the left.

3. In a spinning frame, a thread board having a yarn threading and guiding openingttherein, a yarn guide centered under said opening, said yarn guide having a threading slot lin its front face inclined upwardly in one direction and said thread boardhaving a hook portion overlying said threading slot and inclined upwardly in the opposite direction. I l

4. In a spinning frame, a thread board having a yarn threading and guiding open'- ing inclined in one direction, a yarn guide centered under said opening, and a holder for said yarn uide secured under said thread board and adJustable forward and rearward relative thereto, said yarn guide having a threading slot in its front face inclined in a' direction opposite to that of the guiding opening.

In testimony whereof we have hereunto affixed our signatures.
